由于具有抗干扰能力强和布置灵活机动的特点,伪卫星在增强卫星系统和独立组网为用户提供更高精度导航定位信息方面具有广阔的应用前景。伪卫星空中基站的精确定位是构建伪卫星区域定位系统的一个关键问题。为此,研究了一种基于光电导航的定位算法,综合利用光电探测成像信息和惯性导航信息,根据伪卫星空中基站的特点建立了相应的误差模型,并采用最小二乘法估计位置误差。计算机仿真结果表明所提算法简单,具有较大的实用价值。
Due to its strong anti-jamming ability and flexible arrangement, Pseudo-satellites have broad application prospects in enhancing satellite systems and independent networking to provide users with more accurate navigation and positioning information. Pseudo-satellite positioning of the air base station is a key issue for the construction of Pseudo-satellite positioning system. Therefore, a positioning algorithm based on photoelectric navigation is studied. Based on the information of photodetection imaging and inertial navigation information, a corresponding error model is established based on the characteristics of Pseudo-satellite base stations. The position error is estimated by the least square method. Computer simulation results show that the proposed algorithm is simple and has great practical value.
